There’s a lot that can be said about tonight’s Hullabaloo, the annual street festival happening tonight in Bend’s NorthWest Crossing neighborhood, near the intersection of Mt. Washington and Northwest Crossing drives (see “If you go”).

But let’s go with the thing that turns Hullabaloo from your run-of-the-mill Friday entertainment option into an uppercase MUST: Indigo Girls.

The darn near legendary Georgian folk-rock duo that is Amy Ray and Emily Saliers hits the main stage at 9:30 tonight. In the mid-1980s — several years before the birth of Lilith Fair — these harmonizing, consciousness-raising singer-songwriters emerged with original songs, talent and plenty to say.

What lost or confused soul hasn’t sought solace from “Closer to Fine,” arguably the Indigo Girls’ most enduring song, with lyrics like: “There’s more than one answer to these questions pointing me in a crooked line, and the less I seek my source for some definitive, closer I am to fine.” Of course, I have no literal idea what the heck the lyrics mean, but I sure feel better every time I hear ’em!

As reliable an acoustic duo as Saliers and Ray have been throughout their long career, the two know how to plug in and rock out as well. The Ray composition “Go” (no discernible relation to this entertainment magazine), from 1999’s “Come on Now Social,” is a stirring call to arms, or at least getting involved: “Did they tell you you would come undone when you try to touch the sun? Undermine the underground, ‘You’re too old to care. You’re too young to count.’”

But say the Indigo Girls — despite their pile of gold records and the fact that they’re the only duo to hit Billboard’s Top 40 in every decade from the ’80s to this one — just aren’t your cup of tea. Fine! (You’re farther from it.)

Fortunately, Hullabaloo’s schedule has something for everyone. The music gets going at 4 p.m. with the reggae-influenced pop-rock of Franchot Tone. At 5:30 p.m., it’s the positive rock and hip-hop stylings of Mosley Wotta, charismatically fronted by Jason Graham. At 7 p.m., Portland up-and-comer Redwood Son, led by Josh Malm, will offer soulful Americana with the help of singer-songwriter Laura Invancie.

As always, Hullabloo has plenty to do for kids, including a Kids Stage with African drumming and dance, a drum workshop, a magic show, a reptile exhibit and a performance by the ever popular Janellybean, and the Kids Zone, which will host bouncy houses, giant street puppets and a petting zoo.

Finally, beginning at 4:25 p.m., sharply dressed cyclists will be zipping around the neighborhood during the seventh annual NWX Criterium.

All of the dancing, bouncing, petting and racing making you hungry? Head on over to the food court, where Thai on the Fly, Demetri’s, Parilla Grill, Jumbo Tamales, Dump City Dumplings, Famous Kettle Corn and other fine food purveyors will have what you need. Thirsty? (Of course you are.) Deschutes Brewery, Bendistillery and Atlas Cider Co. will be at Hullabaloo, too. Too much to drink? From 6-11 p.m., Bend Tour Co. will offer a free shuttle service between 900 N.W. Wall St., downtown and the vicinity of La Rosa. If you’re driving your own vehicle, there’s plenty of on-street parking in the area, or you can park at Summit High School, 2855 N.W. Clearwater Drive, Bend.
